gelatin duplicating

[′jel·ət·ən ′dü·plə‚kād·iŋ]
(graphic arts)
A gelatin process in which the item to be reproduced is typed or drawn on a hard-surfaced master with inks containing aniline dyes; the master is then placed face down on a gelatin surface, and the dye is transferred to the gelatin within seconds; when blank paper is pressed against the gelatin, a small amount of the dye is released and a copy made.
